* Adding class for generating all subsequences from a given List * Fix test data format * Fix braces wrong placement * Fix "Utility classes should not have a public or default constructor." * Fix checkstyle " Class Subsequence should be declared as final." * Renaming class Subsequence to SubsequenceFinder. Refactored test to Parametrized test. Fixed input parameter as final. * Fix formatting * Fix formatting * Fix formatting * Fix import ordering * Renaming method generate all. Renaming test method. Adding duplication test. Renaming TestData to TestCase. * Fix formatting * style: add assertion to avoid potential infinite loop --------- Co-authored-by: Piotr Idzik <65706193+vil02@users.noreply.github.com>
